To @ZZ whom, t may concern.- Y

Be it known that I, GARRIT HIGBTE, a citizen of the UnitedStates, residing in county of Kings, and State of New York, have invented a certain new and useful Improvement in Liquid-Seal Pails, of which the following is a specification.

rl `he improvement relates to receptacles having an annular trough surrounding the upper edge, into which a depending lip or iange on the cover is received. Water, or a liquid disinfectant poured into the annular trough, forms a seal between the interior of the vessel and the external atmosphere, effectuall y preventingthe escape of offensive odors or germs of disease given o by the contents. By providing a drain-tube'from the trough, with its discharge orifice directed outward from the body of the pail and closed bya stopper, which may be a plug of cork attached to an adjacent portion of the pail by a short iiexible connection, many serious objections to pails of this class are avoided.

The freezing of the liquid in the trough when the pail is placed out of doors in winter weather is a source of much annoyance, r,it being impossible to empty the trough .without spilling the contents of the pail. In myimproved form, the water in the trough may be drained away, and the trough re-tilled upon bringing the pail again in-doors.

My pail may be emptied more neatly than the old forms by first removing the plug and allowing the liquiddisinfectant to escape, and then throwing out the contents, thus avoiding the spilling of the disinfectant in the act of emptying the pail.

It is often desirable to remove the liquid from the trough for the purpose of replacing it with fresh disinfectant without removing the cover or disturbing the contents, or too much liquid may have been inadvertently poured into the trough and it is necessary to remove a portion. These changes can be made with perfect cleanliness by the use of my improvement.v

I mount' the trough with its upper edge lower than the upper edge of the pail, insuring that the bruising by contact with the ground when the pail is reversed shall be borne by the edge of the pail without injury to the trough. Braces of heavy sheet-iron are Brooklyn,

attached to the exterior of the pail at properly spaced points below the trough to aid in supporting the latter. They extend up around the angular lower edge nearly to the top of the trough. At the opposite points in the circumference the braces are continued still higher and serve as ears for the attachment of the bail. The inclined drain-tube is protected against injury by two braces similar to those first described, set on each side of the tube, with sufficient space between to allow the cork to be easily removed and replaced.

My improved pail is particularly 4well adapted for use in hospitals where contagious diseases are treated, and it is of the greatest importance that the dej ecture be immediately covered and sealed.

The accompanying drawings form a part of this specification.

Figure lis a side elevation of the pail. Fig. 2 is a vertical section at right angles to Fig. 1. Fig. 3 is a vertical section of a portion on a larger scale. It is on the line 3 3 in Fig;

2. Fig. 4.' is a similar view of a portion on the line 4 4 in'Fig. 1.

Similar V letters of reference indicate the same parts'in allthe figures.

A is the body of a pail formed of sheet-iron, and slightly tapered, as shown, and A is the bottom, .attached in the ordinary manner.

B is a sheet-iron ring surrounding the pail near the top. In section, it is I ^shaped, with a downwardly projecting flange at the end of the horizontal portion, by which it is soldered or riveted to the body. This lower portion is marked B. The horizontal portion is marked B2. and forms the bottom of the trough. Another portion B3 extends upward, and with the portion A2 of the pail body forms the vertical walls of the trough. The edge of the lportion B3 is smoothly finish-ed by being turned over an inclosed wire in the wellknown manner, and is somewhat lower than 'the similarly formed edge of the pail so that the trough is protected lwhen the pail is reversed and struck against any obj ect to loosen the contents. A

C, O, are braces of heavy sheet-iron, riveted to the body at c, c. They extend outward angularly, and are bent upward'around the projecting angle of the trough and are secured to zthe latter at c', c. Two of these braces ICO C', C', are set one on each side to inclose the drain-pipe, to be presently described, and protect it from being bruised or broken by striking against surrounding objects, and also lessen the liability of the stopper to be accidentally displaced in the rough handling to which such receptacles are subjected. The two braces C2, C2, at opposite points in the circumference are extended upward beyond the edge of the trough, and are provided with holes c2 into which the hooked ends D of the bail-wire D are engaged.

D2 is the ordinary wooden handle encircling the mid-length of the bail. f

I is the cover, larger in diameter than the top of the pail body, and provided with a handle I. It has an annular depending lip or flange I2. at its periphery which en gagesin the trough and reaches nearly to the bottom B2 of the latter, when the cover comes to rest upon the top of the pail. Pieces of sheet metal i, i, having inwardly inclined outer edges, are soldered to the under face of the cover to aid in centering the latter.

M is a short tube set in the bottom B2of the trough and extending downward and outward between the braces C', U', above described. It is closed by a cork or other stopper N attached to an adjacent portion of the pail by a light chain N sufficiently long to allow the cork to be easily removed and replaced.

The stopper N being inserted, the disinfectin g or antiseptic liquid is poured into the trough until it is nearly-filled and the pail is ready for use. Immediately upon receiving the offensive or deleterious matter the cover is replaced, with its flange I2 engaged in the trough and extending well down into the liquid, thus forming a seal. In this condition the pail is safe, and may be removed and emptied when convenient, or it may remain in the room until lled. In the latter case it may be desirable to renew the liquid in the trough at intervals. This may be accomplished by loosening the stopper and allowing the liquid to escape slowly into any convenient vessel, care being taken to stop the flow before the seal has been broken. The trough may then be again filled with fresh liquid.

The inclination of the tube M away from the oppositely inclined body ot' the pail allows the liquid to be discharged without danger of wetting the floor.

The construction shown renders the pail cheap, light, strong and cleanly.

I claim as my invention- 1. In a liquid seal pail, the cover I and depending flange I2, the annular trough, formed by the upper portion A2 of the body and the portions B2 and B2 of the ring, in combination with the drain-tube M set in the portion B2 ol' the trough and projecting downwardly from the latter and outwardly from the oppositely inclined surface of the pail, to direct the drainage away from the pail and with the stopper N for closing the tube, all substantially as herein specified.

2. In a liquid seal pail, the cover I and depending flange 12, the annular trough, formed by the upper portion A2 of the body and the portions B2 and B3 of the ring, in combination with the draintube M set in the portion B2 ot' the trough and projecting downwardly from the latter and outwardly from the oppositely inclined surface of the pail, to direct the drainage away from the pail the stopper N for closing the tube, and with the braces C', C', located one on each side of the said tube to protect it against accidental blows and also to support the trough, substantially as herein specified. j

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
